> HIVE-17563 reimplemented metrics using native nio interfaces. It used the assumption
that{{Files.move()}} is atomic operation. It turns out that by default it isn't, unless {{ATOMIC_MOVE}}
option is specified. Otherwise the destination file is unlinked and then the source file is
copied.
> This may cause test failure since the file may be temporarily unavailable.
